    Yes, there is no problem installing the server kernel with the desktop version of Ubuntu.
    Don't try to make something "fast" until you are able to quantify "slow".

    Wow, the Idea poster in that link sure started a war.

    Anyways, I had always assumed that 3-3.5GB was the max for 32bit. Never knew this...

    EDIT: btw, why am I unable to thank vom (or anyone in this thread)?

    wow, I considered that cause lost and did not come back to that page anymore

    I have solved it by buying 8 GB ram (after Gigabyte suddenly updated the specs for my mainboard from 4 to 8 GB - probably a courtesy of AMD CPU built-in DDR controllers, and now I'm running quite happily on 64-bit (as far as the horrible 2D support of ATI binary driver goes).
    I'm also running the 64-bit Flash (the alpha version), and it's very good - but that is just very recent development.

    That said, if I could not stuff my mainboard with 8 GB ram, I would have to go PAE with other distro, or own compiled kernel (or a new mainboard).

    Hey, thanks. I really am learning a lot.
    Another round of Ubuntu for my friends here!

    Re: 32 bit Ubuntu with 4GB+ of memory

    I am trying option 2.1 (adding the server kernel). Here is my output:

    Code:
    Reading package lists... Done
    Building dependency tree       
    Reading state information... Done
    E: Couldn't find package linux-restricted-modules-server
    Is that normal or is something amiss?

    (I am running 8.10.)

    Re: 32 bit Ubuntu with 4GB+ of memory

    I'm runnning 32 bit Ubuntu 8.04 with a Core Duo processor (32 bit) and 4 GB of memory. I installed and am running the server kernel, but free is still showing the same amount of memory as the generic kernel, ~3.2 GB. Ideas?

    PAE is really not that much slower.

    Yes, (useless) artificial memory bandwidth tests suffer a little, but for real-world applications there is just a random +- 1%:
